Addiction or addiction is characterized by repetition, compulsiveness, search, or use of a substance even though the effects and consequences are not desirable. Addiction is a mental or emotional dependence on a substance. Nicotine is known as an addictive substance in tobacco, and experts are researching other substances that contribute to tobacco dependence.
Regular use of tobacco products causes addiction to many users. Nicotine is a substance found in tobacco, and the addictive effect is the same as heroin and cocaine.
- When used with a small amount, nicotine provides a pleasant feeling that makes smokers want to continue smoking. Nicotine works on brain chemicals and the central nervous system, affecting the mood of smokers. Nicotine works like other addictive drugs, by flooding reward circuit brain with dopamine. Nicotine also triggers adrenaline, accelerates heart rate and increases blood pressure.
- Nicotine reaches the brain in a few seconds after sucking, and the effect begins to disappear within minutes. This is the reason why smokers light their cigarettes again. If smokers do not immediately smoke again, the symptoms of "cravings" will appear and worsen over time.
- Smokers generally suck 10 times of 1 cigarette. A smoker who spends 1 pack per day experiences 200 "hits" of nicotine per day.
- Smokers usually become addicted to nicotine and suffer from "sakau" symptoms (physical and emotional) when they stop smoking. Symptoms include irritability, anxiety, headaches, and difficulty sleeping. The sign of dependence is where a person continues to smoke even though he knows that smoking is bad for health, affects life, health, and his family. In fact, most smokers actually want to quit. If you want to stop but don't do it, it might mean you are addicted.
Experts are also examining chemicals in tobacco that make smoking difficult to stop. In animal brains, tobacco smoke causes chemical changes that cannot be explained by the effects of nicotine.
On 1 cigarette, the average nicotine level smoked by smokers ranges from 1 - 2 mg. But cigarettes themselves contain more nicotine. The amount of nicotine sucked depends on how you smoke, how much you suck, how much you suck and other factors.
All forms of tobacco have nicotine and other chemicals that are easily absorbed by the lungs by smoking and by mouth with chewing tobacco. Nicotine will quickly spread throughout the body.
How strong is nicotine addicted?
About 70% of smokers want to quit and about half try to quit each year, but only 4 - 7 percent have managed to stop completely without help. This is because smokers are not only physically dependent on nicotine, but also emotional dependence that causes recurrence after stopping.
Smokers may associate smoking with social and other activities. Smokers may also use tobacco to deal with unpleasant feelings, which can make it difficult for some smokers to quit. These factors make smoking more difficult to stop.
In fact, the possibility is more difficult to stop smoking than to stop using cocaine or opiate like heroin. Experts have examined 28 different studies on people who try to stop using substances that make them addictive. (Many people have other support such as behavioral therapy, so the success rate is higher than without help at all.) About 18% managed to stop consuming alcohol, and more than 40% managed to stop using opiates or cocaine, but only 8% managed to stop using alcohol. managed to stop smoking.
What is the effect of nicotine on the body?
Nicotine is poison, and high doses of nicotine can kill by stopping the muscles that humans use to breathe. But smokers usually suck a little nicotine level so the body can process it quickly. The first dose of nicotine can make a person feel refreshed, and the next dose makes you feel calm and relaxed.
Nicotine can cause new smokers and regular smokers who smoke too much, feel dizzy and nauseous. Normal heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and decreases blood flow in the legs. Nicotine plays a role in increasing the risk of heart disease and stroke, but other substances in cigarette smoke have a greater role.
Many people misunderstand that nicotine is a substance in tobacco that causes cancer. This causes some people to avoid using nicotine replacement therapy to stop smoking. In fact, nicotine is a substance that is addictive to tobacco, but not what causes cancer.
Research shows that nicotine affects the activity of some normal cells and cancer cells. Some animal studies have shown that nicotine supports the growth and spread of tumors, but whether this happens to humans is not known for sure, and more research is needed.
